Is it possible to convert a Bitmap into an Image?

I'm playing with Clip and Draw components can someone explain me why this doesn't produce a rounded shape rectangle?

Container(width = 400.dp, height = 400.dp) {

Clip(shape = RoundedCornerShape(20.dp)) {

Draw { canvas, parentsize ->

val outer = Rect(10f, 10f, 100f, 100f)

canvas.drawRect(outer, paint)

}

}

}

Hello! The latest Jetpack Compose minor release, dev06, has just dropped and you can get it now on Google’s Maven Repository. Release notes are available at https://developer.android.com/jetpack/androidx/releases/compose and https://developer.android.com/jetpack/androidx/releases/ui. Please note that the majority of the documentation including codelabs, tutorials, and samples will only be updated for major releases so you may notice some discrepancies if you’re using the latest version of Compose. Feedback is always welcome; please log issues at https://issuetracker.google.com/issues/new?component=612128!

Hi ya'll any guess when the Compose support for better lifecycle awareness will drop? I'd eagerly use it (though currently onCommit and misc onStop glue is working fine.

What's the point of the

indent

parameter? Can't we just add a left offset with padding?

@Composable 
fun Divider(
    modifier: Modifier = Modifier.None, 
    color: Color = MaterialTheme.colors().surface, 
    height: Dp = 1.dp, 
    indent: Dp = 0.dp
): Unit

I'm getting NoSuchMethodError setContent on

0.1.0-dev06

Is this a known error? I also get

e: java.lang.IllegalStateException: Backend Internal error: Exception during code generation

when adding Text Style

Hey folks, is there some ideia of how it will be the integration between Compose and Motion layout? I've been playing with both and I was wondering that.

Hey composers, what is the alternative to

DrawShape

now?

What is this voodoo magic (luckily it was just a hacky function I am not using)

TextButton and OutlinedButton's children aren't updated by

@Model

classes. I suspect that the

noinline

might have affected this. It works okay using a plain button

Is it normal that AdapterList is overlap with Button? And, when I try to click Button more than 20 times, VerticalScroller is fine. But, in AdapterList, my app is stopped with java.lang.IndexOutOfBoundsException: Index: 8, Size: 8. And whatever the numbers are, it just says Index: 8, Size: 8. Plese someone correct my code. Thank you.

AS now complains about method name convention with @Composable (did not do this before)

How can I draw an image now that DrawImage is gone?

Seeing some weirdness when using

ImagePainter

to display an image. Code in thread..

Material Icons Extended going to be sucks for file size.

Is this a bug or not. The Box does not produce a circular shape if you do this

Box(modifier = modifier + ImagePainter(image = image).toModifier(),
            shape = CircleShape,
            border = Border(borderWidth, borderColor))

I am getting a compiler backend exception when compile my code

kotlin.UninitializedPropertyAccessException was thrown at: org.jetbrains.kotlin.ir.declarations.impl.IrDeclarationBase.getParent

. Excepton in thread. Any idea how to fix it ?

Can I pass a class annotated with

@Model

into a Composable without having it recompose when something changes?

Hey guys, do we currently have any way to display video with jetpack compose?

Can you rotate counter-clockwise using the Canvas provided by compose? With legacy view system a negative rotation angle meant rotating counter-clockwise. I am trying to do the same with compose but no success.

Hey guys, I'm getting a NoSuchMethodException on any @Preview I attempt to use after upgrading to dev06.

composeOptions {
        kotlinCompilerExtensionVersion = "0.1.0-dev06"
        kotlinCompilerVersion "1.3.61-dev-withExperimentalGoogleExtensions-20200129"
    }
    buildFeatures {
//        viewBinding = true
       compose true
    }

Anyone else experienced this?

Hello! Someone know how I can scroll at the end of an AdapterList (or a VerticalScroller if it isn't possible with an AdapterList)?

I wanted to ask folks bit of a OT but related to paradigm shift compose will bring, i.e. immutable models. I like this, but ergonomics are very poor imo, given a nested model like this

data class State(
    val items: List<Item> = emptyList(),
    ...
)

sealed class Item
data class HeaderItem(val titleRes: Int) : Item()
sealed class ServiceItem : Item() { ..
data class SimpleItem(..) : ServiceItem
data class FormItem(val textItems: List<TextItem> = emptyList()) : ServiceItem

-- lets say now I need to change text item inside a form item with mutable models code is pretty neat in kotlin

state.items
    .firstOrNull { it is FormItem && item.service.id == serviceId }
    ?.let { it as FormItem }
    ?.textItems
    ?.firstOrNull { it.id == textItemId }
    ?.apply {
        value = text
        validity = FormItem.TextItem.Validity.PENDING
    }

with immutable obviously you need to create copies

setState {
    copy(
        items = items.map { item ->
            if (item is FormItem && item.service.id == serviceId) {
                item.copy(
                    textItems = item.textItems.map {
                        if (it.id == textItemId) {
                            it.copy(value = text, validity = FormItem.TextItem.Validity.PENDING)
                        } else {
                            it
                        }
                    })
            } else {
                item
            }
        }
    )
}

tbh thats some BS code -- all the nested copying, or returning identity in map. I must be missing something. So I was wondering, is kotlin missing some sugar for this, or are immutable models at UI level irrelevant if we can enforce only main thread can touch them? Or maybe I think I've read redux/react people denormalize their states?

Beta-build does not have Compose support, please download 4.1 Canary 2 instead 🙂

Jetpack Compose Question: I am trying to get a android.ui.material.button to look pressed. How is that done in compose?

Jetpack Compose Question: Is there an easy place to find the modifiers for various widgets?

I see recommendations for using Compose and things like Room in the same project by isolating Compose to another module. I’m in Android Studio. I create a new module. Is this uspposed to be library module or what? I created Android App module but now can’t get my one module’s Activities to be able to

import mycomposemodule.testactivity

. How do I accomplish this? I’m trying to add Compose functionality to an existing application that uses Room and other stuff.

dev06
